Cyclone is a library of PureData classes, bringing some level of
compatibility between Max/MSP and Pd environments. Although being
itself in the early stage of development, it is meant to eventually
become part of a much larger project, aiming at unification and
standardization of computer musician's tools.
In its current form, cyclone is mainly for people using both Max and
Pd, and thus wanting to develop cross-platform patches. In this
respect, cyclone has much in common with Thomas Grill's flext, and
flext-based externals. While flext enables developing new
cross-platform classes, cyclone makes existing classes cross-platform.
Cyclone also comes handy, somewhat, in the task of importing Max/MSP
patches into Pd. Do not expect miracles, though, it is usually not an
easy task.
